What are Mold core and cavity inserts

Mold core and cavity inserts are components of a mold used in the manufacturing of plastic and metal parts.

A mold core (sometimes small inserts we call core inserts) is the internal part of the mold, which is normally located at the core side (moveable side). This creates the internal features of the part being molded. The core is typically made out of steel, such as 1.2344, S136, etc., and is typically removable from the mold plate (B plate or pocket plate).

A mold cavity insert has the same function as core insert, but is located on the fix side. It is the external part of the mold that creates the external shape of the part being molded. The cavity insert is typically made out of steel, such as NAK 80, S136, 1.2344, and H13, and is typically removable from the mold.

 

Both the mold core and cavity insert are typically made using the processes of EDM (lavorazione a scarica elettrica) and CNC (computer numerical control) machining. The core and cavity inserts are then assembled into a mold base to get the complete stampo in plastica. The mold is then used in the injection molding or casting process to produce the desired parts.

Of course there are many manufacturing processes to make plastic mold, such as lathe machining, grinder machining, polishing, wire cutting, milling etc. but CNC and EDM machinings are the most improtant manufacuring process to make an injection molding, belew are briefly explain for EDM and CNC machining:

EDM:

  • First, a mold design is created in 3D modeling software.
  • The working piece (cavity and core steel) is then loaded into the EDM machine, which uses electrical discharges to erode the surface of a conductive material (such as steel or aluminum) to create the desired shape of the core or cavity insert.
  • The finished working piece is then polished or textured according to requirement.

CNC:

  • The process is similar, but instead of using electrical discharge machining, a CNC machine uses cutting tools (such as end mills or drills) to remove material from a block of steel or aluminum to create the desired shape of the core or cavity insert.
  • The finished working piece is then heat-treated to increase its strength and durability, if sue pre-harden steel then no need addtional heat treatment, can move to the EDM machining process directly.

CNC machining process

Both EDM and CNC can produce very precise and accurate parts and are widely used in the manufacturing of mold cores and cavity inserts, one important procedure that needs to explain, the working sequence between EDM and CNC, normally CNC machining will start first, then use EDM machining to remove some of area which CNC machining can not do, for example some corners, ribs, bosses, etc.

Mold Core and cavity insert

Some guideline to manufacture mold core and cavity inserts

When we manufacture the mold core and cavity inserts during mold manufacturing, there are some dimensions that we need to manufacture with some tolerances so that they fit well in the pocket of the insert plate or mold cavity or core.

And this will save some work when we fit the mold cavity and core. High tolerance and good manufacturing technology will save lots of time for the mold master. Below are some manufacturing mold core and cavity insert guidelines that we need to pay attention to to make high-quality plastic mold.

  1. When we make the corner radius In the manual milling machine, make a 0.2-mm  step there; after hardening, we don’t have to grind on the corner when we fit the insert.
  2. For the outside dimension of the muffa cavity or core inserts, the tolerance should be +/-0.015mm; this will be easy fitting into the pocket, smooth, and of good quality.
  3. The tolerance for the hole in the sprue bushing should be H7 (0/+0.015 mm).
  4. The depth of the treading should be 1.5–2 multiplied by the diameter of the tread. In this case, for the M8 screw, the depth of the treading should be 1.5 to 2 multiplied by 8, equal to 12–16 mm.
  5. The guidance of the ejector pin should be about 15-20 mm long; this will make sure that the ejector pins are ejecting smoothly with a long lifetime.
  6. The clearance area for the ejector pins should be 1 mm bigger than the diameter of the ejector pins. For any question about mold, please contact us.

Making injection mold cavtiy and core inserts are not easy, it must be made by a professional mold manufacturer, if you are running a injection molding shop, and need to make some mold cavity and core inserts to replace the old inserts, or if you have a new mold that want to make all of cavity and cores and assembly this in your molding shop, you are welomce to contact us, we can make injection mold cavity and core inserts or completely mold cavtiy and core, moldbase, or completely plastic injection mold for you.

Guidelines to manufacture mold core and cavity plates (pocket plates)

As you already knew mold manufacturing is not an easy job, if you do not have any good team or experience in this field, I suggest you find a profession plastic mold company to support you, you could do the molding process at your side but make the mold outsource, because make plastic mold need very high technical skill for every worker, compared to injection molding process, mold manufacturing needs more manual jobs than injection molding service, and need high technical requirement as well, below is one of manufacturing guideline for A plate of mold.

When we manufacture the core and cavity plates for a plastic mold, there are some dimensions that we need to manufacture with some tolerances so that our cavity and core insert components or our standard mold components can smoothly assembly in to the plate pocket, and the straight guidance blocks can fit well in the mold base, below are some key points that we need to take care during A plate manufacturing.

When we have straight interlocks at each side of mold base (A and B plates), the tolerance for this dimension should be H7 (0/+0.015mm), that the interlocks can easy to the assembly in the mold base but keep high precision guiding function.

The pocket dimensions for the cavity and core inserts, we should follow the tolerance requirement H7 (0/+0.015mm), so that our cavity/core insert can be smoothly guided into the pocket but have precision dimension.

The location of the hole for the locating pin is important, this is assembly with clamping plate, and the dimension must match to the related hole on the clamping plate, so the tolerance for the locating pins must keep in ±0.01mm, the locating pinholes must have related tolerance H7 (0/+0.015mm), so that the locating pin can easily go in.

If the mold has the hot runner system to work properly, the fitting area needs to have a tolerance of ± 0.01mm, please see below explain.

For the o ring track depth, the tolerance is ± 0.05mm, for the o ring track diameter

The tolerance is ± 0.25mm, this is the same requirement for all of o-ring in the mold.

A plate manufcturing

guideline for cavity and core plates (pocket plates or A and B plate)

 

Guideline for the clamping plate manufacturing

When we manufacture the cavity side of the clamping plate, there are some dimensions that we need to control with some tolerances so that our standard mold components and other parts can fit well in the clamping plate.

For the locating pinholes, the tolerance should be H7 (0/+0.015mm)

The hole diameter for the locating ring, the tolerance should be ±0.02mm

The hole diameter for the Hot runner manifold support insert, the tolerance should be ±0.05mm

The height dimension for the air venting groove on the Hot runner manifold support insert, the tolerance should be ±0.01mm

The slot for the locating pin to the sprue bushing, the tolerance should be 0/+0.10mm

clamping plate

Rapporto DFM

Che cosa è il Design for Manufacturing (DFM)

Allora cos'è? Progettazione per la produzione (producibilità)? Perché mi interessa? Queste sono un paio di domande che sentiamo nello sviluppo di un nuovo prodotto, prima della produzione dello stampo, questo Rapporto DFM è una fase importante. Il Design for Manufacturing (DFM) è il processo di progettazione di un prodotto in modo che sia facile ed economico da produrre. Ciò può comportare la semplificazione della progettazione, l'utilizzo di componenti standard e l'ottimizzazione della progettazione per il processo di produzione che verrà utilizzato.

L'obiettivo del report DFM è ridurre i costi di produzione, migliorare la qualità e aumentare l'efficienza. È un aspetto importante del processo di sviluppo del prodotto, in quanto può avere un impatto significativo sul successo complessivo del prodotto. L'idea di base esiste in quasi tutte le discipline ingegneristiche, ma ovviamente i dettagli differiscono ampiamente a seconda della tecnologia di produzione.

Progettazione DFM per la produzione

Progettazione DFM per la produzione

Perché abbiamo bisogno di effettuare un'analisi di progettazione per la produzione (DFM) per un nuovo stampo

UN Rapporto di progettazione per la produzione (DFM) L'analisi è importante per un nuovo progetto di stampo perché aiuta a identificare potenziali problemi di progettazione e produzione prima che lo stampo venga prodotto, è simile a rapporto di analisi del flusso di muffa per un nuovo stampo. Questo può far risparmiare tempo e denaro, poiché è molto più conveniente apportare modifiche al design prima che lo stampo venga costruito, piuttosto che dopo.

UN Rapporto DFM l'analisi comprende un esame dettagliato della progettazione del prodotto e del processo di produzione e può aiutare a identificare problemi quali:

  • Caratteristiche di progettazione che potrebbero essere difficili o impossibili da realizzare
  • Materiali che potrebbero non essere adatti al processo di fabbricazione
  • Processi di assemblaggio inefficienti o inaffidabili
  • Potenziali problemi di qualità che potrebbero sorgere durante la produzione
  • Opportunità di risparmio sui costi che possono essere implementate nel processo di progettazione e produzione.
  • Caratteristiche delle parti che potrebbero essere difficili o impossibili da modellare
  • Angoli di sformo insufficienti per una facile rimozione del pezzo dallo stampo
  • Spessori delle pareti non uniformi, che possono causare deformazioni o altri problemi di qualità
  • Sottosquadri che potrebbero richiedere componenti di stampo aggiuntivi, aggiungendo costi e complessità allo stampo.

Nel complesso, un'analisi del report DFM può aiutare a garantire che la progettazione del prodotto sia compatibile con il processo di produzione e che il prodotto finale soddisfi gli standard qualitativi desiderati. Aiuta anche a ridurre al minimo i tempi e i costi del processo di produzione e può migliorare il tasso di resa del prodotto. Inoltre, aiuta a identificare opportunità di risparmio sui costi e ad apportare miglioramenti alla progettazione che possono portare ad un aumento dell'efficienza, della qualità del prodotto e della redditività.

progettazione per la produzione

Il rapporto DFM è destinato a prevenire:

Penso che questa sia una buona panoramica del concetto generale di cosa DFM (progettazione per la produzione) è. Quindi la domanda successiva è "perché è un problema?" Ci sono diverse possibili risposte a questa domanda.

La prima possibile risposta è che le tecnologie di produzione cambiano continuamente, quindi è difficile tenere il passo con le nuove tecnologie disponibili. Potrebbe essere vero...ma io non sono convinto.

La risposta successiva potrebbe essere che gli ingegneri non sono formati correttamente quando escono dal college. Questa è una possibile risposta, ma sembra che dia la colpa del problema a qualcun altro.

Infine, la risposta potrebbe essere che l'ingegneria non viene più svolta nella stessa struttura in cui avviene la produzione!

Con la produzione che si sposta all'estero, in sedi lontane dall'ingegneria, la collaborazione che esisteva in passato tra ingegneria di progettazione e produzione non avviene più. I progetti vengono creati e poi passati alla produzione per realizzare le parti. Sembra fantastico e molto efficiente, ma non così impeccabile nella pratica.

Come fa un ingegnere a scoprire il problema nascosto dello stampaggio a iniezione? Beh, sfortunatamente, non lo fa. Non vede i problemi finché non progetta una parte e la fa produrre. Detto questo, ora ci sono servizi là fuori per aiutare con il processo di produzione durante la fase di sviluppo del prodotto.

Forniremo un progettazione per la produzione (Rapporto DFM) per ogni parte prima di iniziare la progettazione e la fabbricazione dello stampo.

stampo a iniezione a due piastre

What is two plate injection mold?

Two plate injection mold (2 plate injection mold), Stampo a iniezione a 3 piastre and all of other type of plastic injection molds  are type of molds used in plastic injection molding, in 2 plate mold where two separate mold plates are used to form the mold cavity, one plate we called “A” plate or A pocket plate, which contains the cavity and it is fixing half, and normally we called this cavity side, the other plate is  “B” plate (or core side/movable side), which contains core inserts which is moving half, the ejector systmes is also staying at the core side.

The plastic is injected into the mold cavity through the sprue, and then the B plate is closed against the A plate to form the part. Once the plastic has cooled and solidified, the B plate is opened and the part is ejected. This type of mold is generally used for smaller, simpler parts with minimal undercuts or complex geometries.

Advantages of the Two-Plate Mold

stampo a iniezione a due piastre

stampo a iniezione a due piastre

The beauty of the two-plate design lies in its simplicity. This translates into several advantages:

  • Cost-effective: With fewer parts and a straightforward design, two-plate molds are the most economical option. It makes the two plate injection mold recommended for high-volume production of parts that are less intricate.
  • Easy maintenance: Due to their basic design, two-plate molds are easier to maintain and repair.
  • Fast cycle times: The simple opening and closing mechanism allows for quicker production cycles compared to more complex molds.
  • Suitable for a variety of materials: They can handle a wide range of thermoplastics, making them versatile for various applications.

Disadvantages of two plate injection moulding

While two-plate molds offer numerous benefits, they also have limitations:

  • Gate mark aesthetics: The point where the molten plastic enters the cavity (the gate) can leave a visible mark on the final product.
  • Part complexity: They struggle with parts that have undercuts, deep cores, or threads. These features require additional mechanisms that increase complexity and cost.
  • Runner waste: The runner system attached to the molded part needs to be removed, generating plastic waste.

The Molding Process in Action

The injection molding two plate mold undergoes a precise cycle to produce plastic parts. Here’s a simplified breakdown:

  1. Clamping: This is when the B-side and the A-side are closed securely together to apply high pressure that guarantees a perfect seal.
  2. Injection: The molten plastic will be injected at high pressure through the designated part or the sprue into the mold cavity.
  3. Packing and Holding: After filling the cavity, pressure will be retained to even out the shrinkage of the plastic while it cools.
  4. Cooling: The mold is cooled with water channels to solidify the plastic part.
  5. Mold Opening: The B-side retracts, creating a parting line where the two mold halves separate.
  6. Ejection: Pins or other mechanisms push the finished plastic part out of the cavity.
  7. Runner Removal: The leftover plastic from the sprue and channels (called the runner) might need to be manually removed from the part.

Difference between two plate and three plate mould

A two plate mold and a stampo a tre piastre are different types of molds used in plastic injection molding, with the main difference being the number of plates used to form the mold cavity.

Two plate molds:

Imagine a clamshell. This is the fundamental concept of a 2 plate injection mold. This is made up of two key components. First is the fixed plate or also referred to as the “A-side” and second is the moving plate or the “B-side”.

The magic happens within these two halves. The A-side houses a cavity that replicates the desired shape of the final plastic part. The B-side might have a core that forms internal features or simply acts as a counter to the cavity. These two sides come together to create a sealed enclosure where molten plastic is injected.

  • have two separate mold plates, the “A” plate and the “B” plate.
  • The A plate contains the cavity and core, and the B plate contains the ejector mechanism.
  • The plastic is injected into the mold cavity through the sprue, and then the B plate is closed against the A plate to form the part.
  • Once the plastic has cooled and solidified, the B plate is opened and the part is ejected.
  • This type of mold is generally used for smaller, simpler parts with minimal undercuts or complex geometries.

Three plate molds:

  • have three separate mold plates, the “A” plate, “B” plate and the “C” plate (or runner plate).
  • The A plate contains the cavity, the B plate contains the core, and the C plate contains the runner the runner pusher with ejector at cavity side (this ejector only ejecting the runner which we call runner pusher as well).
  • The plastic is injected into the mold cavity through the C plate (runner plate), and then the B plate is closed against the A plate to form the part.
  • Once the plastic has cooled and solidified, The C plate is opening to pull the runner stick with C plate and then use pusher to ejector the runner off the runner plate, then B plate is opened, and the part is ejected.
  • This type of mold is generally used for larger, more complex parts with undercuts or other features that cannot be formed with a two plate injection mold.
3 plate mold vs 2 plate mold

3 plate mold vs 2 plate mold

In summary, the main difference between two plate and three plate moulds is that two plate mold has the runner which is located on the A or B plate which is on the parting line layer, and ejected out by the ejector systems with part together,  the three plate moulds which the runner will stick with C plate ( runner plate), and later one will be ejected by the pusher, and will be more complex and expensive than two plate mold.

How Does Plastic Injection Molding Work?

plastic injection molding contract manufacturing is a delicate process, which means you need to find a expert injection molding supplier to make your products. This molding process is done by pouring melted plastic resin directly into a mold cavity. This is because high-pressure injection guarantees the detailed formation of the part. The mold cools and the shape becomes solid and fixed.

Ejector pins remove the formed part. The cycle time depends on its sophistication level. CNC-machined molds guarantee accuracy. Automated systems streamline production.

Quality control checks help to ensure that standards are kept up. This method is highly effective in mass production of complex components.

What Are the Steps Involved in Plastic Injection Molding Contract Manufacturing?

In the field of plastic injection molding contract manufacturing, stampo in plastica making comes after prototyping. It is usually made of steel or aluminum. Mold making is done through Computer Numeric Control (CNC) machining. EDM refines intricate details.

Accuracy is very important, and some of parts are made to tight tolerances of 0.05 mm. The cooling channels are incorporated. Ejector pins help in removal of the part.

Polishing helps in improving surface finishes. Cores and cavities which are part of the mold are put together. Mold integrity is checked at the final stage of the process.

Molding Production

Contract manufacturing in injection molding of plastics incorporates high pressure injection. Molding machines use clamping forces which are in tons. The mold is then heated to certain temperatures. This is done by placing the molten plastic into the mold cavity with pressure.

The pressure is kept up until the part has frozen. Mold temperatures are regulated by cooling systems. Operating cycles are smooth and speedy. Part ejection is done by the robotic arms.

This is a way of maintaining the quality of a product or service since the monitoring is done on a constant basis. The volumes of production can be in the thousands of units.

Post-Production

Common finishing steps that are part of post-production in stampaggio a iniezione di plastica contract manufacturing are as follows. Casting is then cleaned through trimming and deburring.

Additional operations such as drilling and tapping are carried out. Coatings like painting and plating increase aesthetics. It may be necessary to assemble a number of parts.

Ultrasonic welding is the process of joining plastic parts. Quality checks ensure the accuracy of dimensions. Packaging is important to guarantee that parts are well protected. New production data are incorporated into documentation. The final product is now ready for delivery.

Controllo di qualità

Quality control in plastic stampaggio a iniezione plays a significant role in delivering high quality products. Inspection begins with dimensional analysis. CMM machines measure parts. Visual inspections identify surface imperfections.

Tensile testing verifies the strength of a material. X-ray inspection reveals internal defects. Control charts are used to measure and track production stability. Every batch also goes through some tests.

The Molding Process: Alchemy of Plastic

That is why plastic cup molds are the real players that remain unseen. These are highly delicate pieces of metal work that create the shape of molten plastic into forms of items seen and used daily. The two most common techniques commonly used in molding of plastic cups are thermoforming and injection molding.

Thermoforming is more appropriate when it comes to disposable cups. Plastics are heated until they obtain softness and can be easily molded. The mold that is usually made of aluminum then presses it do in order to have the shape of the plastic. Another clay is then applied on it before another vacuum or compressed air is used to knock off excess material to form a perfect Cup form. This process is relatively cheaper and efficient when it comes to the manufacturing of disposable cups perhaps in large quantities.

On the other hand, the use of plastic cup injection mold provides more the requirement of solid and reusable cups. In the process, the material, usually plastic in this case is forced under pressure into a hollow mold. The plastic will then crystallize and contract to the shape of the mold that is on the produced item. This process allows for the thickening of the walls of the plastic and formation of new minute designs. This is wonderful for those cups that should technically last several washes and wears.

The Anatomy of a Plastic Cup Mold

A plastic cup mold is much more than just a hollow form. It’s a complex engineering marvel with several key components:

  • Canali di raffreddamento

Channels circulating a coolant, which is often water, are embedded within the plastic cup mold. The rapid cooling allows speedy solidification of the plastic to enable faster production cycles.

  • Core and Cavity

These are the heart of the mold. The core shapes the inside of the cup, while the cavity forms the outside.

  • Ejection System

Once cooled, the cup needs to be ejected from the mold. Pins or plates push the formed cup out, making way for the next cycle.

  • Gating System

This intricate network of channels delivers the molten plastic into the cavity. A well-designed gating system ensures proper flow and minimizes waste.

  • Venting System

As the plastic cools, it traps air. Vents allow this air to escape, preventing imperfections in the final cup.

Beyond the Basics: Innovation in Molds

The world of plastic cup molds is constantly evolving.  Here are a few exciting advancements:

  • In-Mold Labeling

Designs and logos can be directly integrated into the mold, eliminating the need for separate labels.

  • Multi-cavity Molds

These molds create multiple cups simultaneously, increasing production efficiency.

  • Stackable Cup Molds

Plastic cup molds produce cups that can be stacked easily together to save space during transport and storage.

How Many Cavities Should a Plastic Cup Mold Have?

The number of cavities in a plastic cup mold will depend on the specific application and the production volume required. In general, the more cavities a mold has, the more cups can be produced in a single cycle. A single cavity mold will produce one cup at a time, while a multi-cavity mold can produce multiple cups at once.

For high volume production, it is common to use a multi-cavity mold with 8, 16, or even 32 cavities. This allows for a high production rate and can help to keep unit costs low. For lower volume production, a single cavity mold may be sufficient.

It is important to note that a multi-cavity mold can be more complex and expensive to produce and maintain. It may also require a higher level of precision and accuracy in the injection molding process.

How to Save on Plastic Cup Unit Price Using a Plastic Cup Mold

There are several ways to save on plastic cup unit price using a stampo per bicchieri di plastica. One way is to choose a more efficient mold design. For example, a hot runner mold can help to reduce plastic waste and lower production costs. Another option is to use a multi-cavity mold, as this can increase production efficiency and lower unit costs.

Another way to save on unit price is to use a multiple cavities of plastic cup mold. This can help to reduce the cost of production. Additionally, it is important to keep the mold well-maintained and to monitor the injection molding process closely to ensure that it is running efficiently and producing high quality cups, check to know stampo per cassa di plastica.

Stampaggio a iniezione trasparente

La creazione di stampaggio a iniezione di plastica trasparente parte è un insieme di attività complesse che sono diverse da quelle affrontate nello stampaggio a iniezione con materiali non trasparenti. La scelta dei materiali è fondamentale non solo per le loro proprietà, ma anche per le loro prestazioni durante il processo di produzione e nel prodotto finale. Mentre si lavora con materiali non trasparenti, alcuni difetti possono essere nascosti in una certa misura, ma quando si tratta di stampaggio a iniezione trasparente, la precisione dei processi di progettazione e produzione dovrebbe essere perfetta.

Tuttavia, è importante notare che la pianificazione e la preparazione sono molto importanti nel processo di stampaggio a iniezione prima di entrare nei dettagli dei materiali utilizzati. Ciò comporta una corretta preparazione delle materie prime, una corretta calibrazione delle attrezzature, utensili adeguati e procedure di stampaggio adeguate, che sono cruciali nella produzione di parti stampate trasparenti.

Il primo criterio che viene preso in considerazione quando si pratica lo stampaggio a iniezione trasparente è la capacità di vedere le particelle. Le plastiche trasparenti non mascherano i difetti che possono verificarsi durante lo stampaggio rispetto alle plastiche opache. Quindi, è fondamentale mantenere ogni area del ciclo di produzione il più pulita possibile per ottenere la migliore qualità del prodotto finale. È importante conservare i materiali correttamente in modo che non vengano contaminati e che le materie prime siano di buona qualità.

Stampaggio a iniezione di plastica trasparente

Selezione del materiale per il processo di stampaggio a iniezione di plastica trasparente

Quando si tratta di selezionare materiali per traslucidi e stampaggio ad iniezione trasparente, diverse opzioni offrono vantaggi distinti:

Acrilico (PMMA): L'acrilico è un materiale versatile che può essere utilizzato per stampo a iniezione trasparente così come prodotti colorati. È ben noto per la sua atossicità, resistenza ai graffi e resistenza ai raggi UV ed è ampiamente utilizzato in attrezzature per esterni, apparecchi di illuminazione e articoli decorativi. Tuttavia, la rigidità dell'acrilico e la sua natura fragile richiedono un'asciugatura adeguata per evitare l'umidità che influisce sul processo di stampaggio e sul prodotto finale. Vai a Stampaggio a iniezione acrilico pagina per saperne di più sullo stampaggio PMMA.

Polietilene ad alta densità (HDPE): È resistente ai raggi UV e può essere modellato in parti traslucide, il che è un vantaggio dell'HDPE. È più resistente alla rottura dell'acrilico ed è relativamente più economico, quindi adatto all'uso in contenitori, bottiglie e tubi, tra gli altri. Tuttavia, l'HDPE non è raccomandato per applicazioni ad alta pressione a causa della sua relativamente bassa resistenza all'impatto.

Policarbonato (PC): Il policarbonato è trasparente, resistente ai raggi UV e più resistente all'impatto dell'acrilico. È ampiamente utilizzato in indumenti di sicurezza, finestre, contenitori e altre applicazioni che richiedono elevata resistenza all'impatto e trasparenza. Come nel caso dell'acrilico, anche il PC deve essere asciugato prima dello stampaggio a iniezione per ottenere le migliori prestazioni. Scopri di più su Stampaggio a iniezione di policarbonato.

Polieterimmide (PEI): PEI è un materiale ad alte prestazioni che mostra un'eccellente resistenza ai raggi UV, al calore e agli ambienti chimici. È ampiamente utilizzato in applicazioni ad alte prestazioni come strumenti medici, parti di automobili e componenti aerospaziali in cui sono desiderabili elevate prestazioni meccaniche e caratteristiche termiche. Tuttavia, a causa del suo costo elevato e della necessità di processi di produzione specializzati come l'uso di stampi in acciaio, PEI è più appropriato per applicazioni che richiedono elevate prestazioni.

Polipropilene (PP): Il PP è un materiale molto utile caratterizzato da flessibilità, conduttività elettrica e stabilità chimica. È utilizzato in numerosi settori per usi quali tessuti, imballaggi, elettronica e usi chimici. Grazie alla caratteristica a cerniera, il PP è più adatto per applicazioni in cui sono richieste flessibilità e resilienza e non ci si aspetta che la parte sopporti alcun carico.

Gomma siliconica liquida (LSR): LSR è un materiale biocompatibile con buona stabilità termica, chimica ed elettrica. È ampiamente utilizzato in apparecchiature mediche, parti elettriche e industrie di produzione di automobili, dove resistenza ed efficienza sono vitali. Grazie alla sua flessibilità e alle sue caratteristiche migliorate, LSR è adatto per applicazioni in cui sono richieste elevata precisione nello stampaggio e alte prestazioni.

Gomma siliconica ottica (OLSR): OLSR è un materiale avanzato che viene utilizzato per migliorare la trasmissione della luce e la chiarezza delle parti ottiche. Ha migliori caratteristiche di non cedimento e quindi può essere utilizzato in dispositivi per esterni e altre applicazioni in cui il prodotto è esposto a condizioni meteorologiche estreme. Grazie alla sua buona stabilità della trasmittanza ottica nel tempo, OLSR è adatto per parti ottiche trasparenti in cui la trasmissione della luce è importante.

Tutti questi materiali hanno i loro vantaggi e le loro sfide quando si tratta di stampaggio a iniezione trasparente e sono adatti all'uso in diverse applicazioni in vari settori. La scelta dei materiali, la progettazione e le tecniche di produzione sono ben pensate e implementate per produrre parti stampate trasparenti di alta qualità, prestazioni e aspetto.

Polietilene (PE)

L'HDPE è prodotto tramite un processo in cui il petrolio è esposto a calore e pressione ed è un tipo di termoplastico. Mentre l'acrilico ha i suoi vantaggi, l'HDPE ha resistenza ai raggi UV, è incredibilmente versatile ed è facile da modellare. Grazie a questi vantaggi e al fatto che è relativamente più economico da produrre, l'HDPE è comunemente utilizzato nella produzione su larga scala di prodotti come bottiglie, tubi e contenitori.

Resine elastomeriche

Il TPR è una delle resine elastomeriche che sono una combinazione di plastica e gomma che può essere facilmente lavorata tramite stampaggio a iniezione. Il TPR ha usi in prodotti come erogatori di fluidi, tubi flessibili, cateteri e attrezzature che devono avere resistenza a liquidi come gli acidi. Per queste applicazioni, è preferito per la sua flessibilità e capacità di resistere a condizioni difficili.

Poliuretano termoplastico (TPU)

Il poliuretano termoplastico (TPU) è caratterizzato da elevata resistenza alla trazione e allo strappo, morbidezza ed elasticità. Ciò rende il TPU adatto all'uso nello sviluppo di prodotti che devono avere una presa salda e allo stesso tempo essere comodi da tenere. Anche se il TPU è relativamente più costoso delle altre resine, è ampiamente utilizzato per creare parti con attributi simili alla gomma.

Problema comune con gli stampi per iniezione trasparenti

Ecco alcuni dei difetti più comuni che si riscontrano nelle parti in plastica trasparente e le possibili soluzioni:

Le parti in plastica trasparenti sono vulnerabili a diversi tipi di difetti durante il processo di stampaggio. È importante conoscere questi difetti e come evitarli per realizzare prodotti trasparenti di alta qualità. Ecco alcuni dei difetti più comuni e le rispettive soluzioni: 

1. Trappole d'aria

Quando si modella la resina, non è raro che nel materiale si incastrino sacche d'aria, che saranno evidenti nel prodotto finale. Questo è solitamente il risultato di una scarsa ventilazione o di una bassa pressione durante l'iniezione del materiale.

Soluzione: È possibile ridurre le intrappolamenti d'aria e aumentare la trasparenza del prodotto migliorando la progettazione dello stampo, incorporando i canali corretti per lo sfiato e aumentando la pressione di iniezione. 

2. Linee di flusso

Le linee di flusso sono quelle linee o striature sulla superficie delle parti in plastica trasparente che si formano a causa della differenza nel flusso del materiale durante il processo di stampaggio a iniezione. Queste linee possono rovinare la bellezza del prodotto.

Soluzione: Modificando la velocità e la pressione di iniezione, nonché la progettazione dell'ugello, è possibile ridurre al minimo le linee di flusso e migliorare la finitura superficiale generale del pezzo. 

3. Segni di affondamento

I segni di ritiro sono piccole rientranze sulla superficie del pezzo in plastica, solitamente causate da differenze nella velocità di raffreddamento o da un riempimento non corretto della resina durante il processo di solidificazione.

Soluzione: Ridurre i tempi di raffreddamento, controllare la pressione di compattazione e applicare misure adeguate di controllo della temperatura dello stampo può contribuire notevolmente a ridurre i segni di ritiro e a migliorare la qualità del pezzo.

4. Graffi superficiali

Tra i difetti superficiali che si possono osservare rientrano graffi o segni causati dalla manipolazione o dall'espulsione delle parti stampate, che possono influire sul grado di trasparenza e sulla finitura superficiale delle parti.

Soluzione: Procedure di manipolazione ed espulsione adeguate, agenti distaccanti o trattamenti superficiali possono aiutare a evitare graffi superficiali e garantire la trasparenza del prodotto. 

5. Nebbia o nuvolosità

L'appannamento o l'opacizzazione dei componenti in plastica trasparente può essere causato da diversi fattori, come l'essiccazione inadeguata della materia prima, la contaminazione o l'elevato contenuto di umidità durante il processo di stampaggio.

Soluzione: Per evitare fenomeni di velatura e ottenere pezzi nitidi e trasparenti, è necessario prestare attenzione alla corretta manipolazione e conservazione dei materiali, all'uso di resine secche e alle corrette condizioni di lavorazione.

Se questi difetti vengono corretti e si applica la soluzione giusta, i produttori possono creare parti in plastica trasparente con buona nitidezza e valore estetico.

Suggerimenti per la selezione e la progettazione della finitura superficiale per stampi a iniezione trasparenti

Per quanto riguarda la chiarezza delle parti in plastica, è molto importante scegliere la giusta finitura superficiale. La levigatura e la lucidatura manuali sono utili per i design più ruvidi che non hanno dettagli fini, ma non sono efficienti per creare prodotti trasparenti. Se la tiratura di produzione è bassa o se il prototipo o il progetto è un pezzo unico o irripetibile, allora la finitura SPI-A2 potrebbe essere adeguata, specialmente se la finitura superficiale non è una considerazione quando si valuta un prototipo. Si è anche visto che se il concetto di finitura superficiale viene rinviato al livello di produzione, allora si potrebbero risparmiare molto tempo e denaro.

Per parti trasparenti piatte o quasi piatte come finestre o lenti, la migliore finitura superficiale è il rivestimento in resina. Tuttavia, è fondamentale comprendere che l'uso di un agente distaccante è svantaggioso per la superficie della parte e non dovrebbe essere utilizzato. È importante notare che i tempi di consegna e i costi della finitura superficiale possono variare a seconda del progetto.

Per quanto riguarda le raccomandazioni per la progettazione delle parti trasparenti o traslucide, è necessario tenere conto di diversi aspetti. È inoltre importante mantenere costanti gli spessori delle pareti in tutta la parte per mantenere una trasparenza uniforme. Altre considerazioni includono la progettazione di guide di scorrimento delle porte sufficientemente larghe e il posizionamento delle porte in modo tale che si adattino al processo di contrazione. La mancanza di angoli acuti, in particolare per i prodotti in PC, aiuta a evitare spazi vuoti e a rendere le transizioni più chiare.

Inoltre, mantenendo una superficie liscia dello stampo e un raffreddamento adeguato si ridurranno i difetti superficiali e il calo della trasparenza della plastica in stampaggio a iniezione di plastica trasparente. Per ottenere consigli di progettazione più specifici per lo stampaggio a iniezione trasparente, si consiglia di leggere ulteriori informazioni sull'argomento.

Per questo motivo la scelta del materiale utilizzato per la stampo paraurti durante il processo di fabbricazione è altrettanto critico, per usare un eufemismo. Ogni materiale ha il suo set di idee buone e cattive che hanno tutte un effetto diretto sulle caratteristiche e le prestazioni complessive dello stampo del paraurti dell'auto.

Date un'occhiata ad alcuni dei materiali utilizzati per le modanature dei paraurti.

Alluminio

Gli stampi per paraurti in alluminio sono noti per essere leggeri e consentire cicli più rapidi durante il processo di stampaggio a iniezione, garantendo così una migliore produttività ed efficienza in generale.

Lo stampaggio del paraurti che utilizza l'alluminio può trarre vantaggio da un'eccezionale conduttività termica che può ridurre i tempi di ciclo e garantire un raffreddamento più rapido. Vale anche la pena notare che gli stampi per paraurti in alluminio hanno prezzi più bassi, il che è un grande vantaggio per i produttori.

L'unico inconveniente è che questi stampi non sono molto durevoli e la maggior parte di essi richiede frequenti sostituzioni o riparazioni a causa dell'usura.

Materiali compositi

La plastica rinforzata con fibra di carbonio e la fibra di vetro sono due dei materiali compositi che stanno iniziando a catturare l'attenzione dei produttori di stampi per paraurti.

Questi materiali vantano resistenza, durevolezza e leggerezza, il che li rende una scelta allettante per la modanatura del paraurti. I compositi sono anche da riparare, il che li rende utili per molto tempo.

Tuttavia, gli stampi per paraurti realizzati in materiali compositi spesso richiedono elevati costi iniziali di produzione, in quanto richiedono attrezzature e tecniche specializzate.

Stampi ibridi

Gli stampi per paraurti ibridi combinano diversi materiali, ognuno dei quali ha una funzione o uno scopo particolare nel processo di fabbricazione. Uno stampo, ad esempio, può presentare una cavità con inserti realizzati in materiali compositi o alluminio e un'anima in acciaio.

Questi modelli ibridi offrono i vantaggi di ogni materiale per garantire convenienza e prestazioni migliori.

L'unico inconveniente è che uno stampo per paraurti ibrido tende a essere più complesso e richiede considerazioni aggiuntive in termini di progettazione e metodi di produzione specializzati.

Acciaio

L'acciaio è senza dubbio l'opzione tradizionale e più popolare per lo stampaggio di paraurti, grazie alla sua eccezionale resistenza e durata. Uno stampo per paraurti in acciaio può sopportare pressioni e temperature elevate durante la procedura di stampaggio a iniezione senza deformarsi o deformarsi.

Ma la produzione e la manutenzione degli stampi in acciaio possono risultare un po' costose, per non parlare del fatto che il loro peso potrebbe ostacolare anche il processo di fabbricazione.

Termoplastici

I termoplastici possono offrire diversi vantaggi quando vengono utilizzati per uno stampo per paraurti. Questi materiali sono noti per la loro elevata flessibilità in termini di progettazione, facilmente riparabili o modificabili se e quando necessario.

Gli stampi vantano inoltre un'eccezionale stabilità termica, il che significa che possono mantenere la loro forma senza deformarsi o deformarsi anche se esposti ad alte temperature.

L'unica preoccupazione è che spesso sono meno durevoli degli stampi compositi o in acciaio, il che ne limita l'uso a progetti complessi di stampi per paraurti di automobili e ad ambienti ad alta produzione.

La scelta del materiale giusto per lo stampo del paraurti può fare una grande differenza nel risultato finale, che può tracciare una linea sottile tra sopravvivenza e perdita di vite umane durante le collisioni tra veicoli.

Se stai cercando uno stampo a iniezione personalizzato o stampo per auto per la tua attività, trova un Stampo ad iniezione cinese l'azienda sarà una delle migliori opzioni.

 

Plastic stool Mould

What is plastic stool mould for?

Plastic stools are a very popular yet versatile furniture pieces that can be found in homes and offices, and public places all around world.. They were easy to clean and often more affordability than their wooden or metal counteracts. One of the key factor in-the production of plastic stool is the using of a plastic stool-mould, which determine the shape and design off final product. In this article, we delves into the world of plastic stool-mould, exploring their varying types, the manufacture processes and the benefits them offer.

Type of plastic stool moulds

There are several different types plastic stool mould that cans be used to create stools, each with its own unique characteristic and disadvantage. The most commonly types of moulds including inject moulds compressor moulds and blowing moulds.

Injection moulds were used produced plastic stool with complicate shapes and intricate details! This types of mould are created by inject molten plastics into a cooling mould, which is then allow to cooled and solidify. Injection moulds is highly accurate and can produces stool with a high levels of consistencies and precisions. Them are also able to produced stools in-large quantities, making them a popular chooses for mass producing.

Compression moulds, on another hand, is used to create plastic stools with simpler designs and fewer detail. This types of mould are creating by place a pre-heat pieces of plastic between two cooled mould halves and apply pressuring to shape the plastics into desirous forms. Compression mould is generally lesser expensive and faster produce than injection mould, making it a good chooses for smaller productions run or for produce basic stools.

Blow mould, are uses to create hollow plastic stools like those with cut out designs or those that meant be light-weight and portable. These type of mould is created by injecting molten plastic into a cooling mould and then using pressured air to blow the plastic out into the desirous shape. Blow moulds were typically used for creating stools with unique-designed and is not suitable for mass produce.

Plastic stool mould manufacturing process

Processing of creating a plastic stool use mould begin with designing and creation of mould itself. This proses typically involve using computer-aiding design (CAD) softwares to create detailed 3D model of stool. Moulds are fabricate using various materials, like steels aluminums or copper, depend on specific requirements of stool. Once plastic stool mould were creating, we begin manufacturing processes. This typically involve following step.

Melts the plastic: The plastic used for create the stool is melted down and inject or placed into mould.

Coolings and solidifying: The molten plastic allowed to cool and solidify, taking on shape of moulds.

Removes the stool: Once plastic were solidify, mould is opened and stool removed.

Finishing touch: Stools may undergo additional process, such as sanding or paint, to give it finish look.

Using a plastic mould creates plastic stools offers several benefitses over other manufacturing methods. One main advantage is able producing stool with high levels consistencies and precision. Moulds allows for creation stools with complex shapes and intricate details, and using CAD softwares ensure the finished products meet desirous specifications.

Another benefitor using mould are the ability produce stools in large quantities! Moulds can be used mass produces stool, making them cost-effective choosing for businesses and manufacturer.
